: (2) new system call entry points for non-blocking read and write, then
: libc_r can completely ignore FNONBLOCK and just use the new entry
: points.

: I'm thinking (2) might be the only real solution.
Something like this:
nbpread(int d, void *buf, size_t nbytes, off_t offset)
nbpread(int d, const void *buf, size_t nbytes, off_t offset)
(same arguments as pread/pwrite). offset can be -1, indicating that the
current offset should be used and updated. The function would perform
the operation non-blocking regardless of the non blocking setting on the
file pointer.
libc_r would then use the new entry points and would not mess with
the non-blocking flag on the FP at all.
